Infant

An infant (from the Latin word infans, meaning “unable to speak” or “speechless”) is the very young offspring of a human. When applied to humans, the term is usually considered synonymous with baby, but the latter is commonly applied to the young of any animal. When a human child learns to walk, the term toddler may be used instead. The term infant is typically applied to young children between the ages of 1 month and 12 months; however, definitions may vary between birth and 3 years of age.
